一, 聲明開(kāi)始時(shí)間和結(jié)束時(shí)間
let create_time = "2016-08-12 8:34:21"
let end_time = "2016-08-14 09:32:08"
二, 聲明方法將秒數(shù)轉(zhuǎn)為 時(shí):分:秒
func getHHMMSSFormSS(seconds:Int) -> String {
let str_hour = NSString(format: "%02ld", seconds/3600)
let str_minute = NSString(format: "%02ld", (seconds%3600)/60)
let str_second = NSString(format: "%02ld", seconds%60)
let format_time = NSString(format: "%@:%@:%@",str_hour,str_minute,str_second)
return format_time as String
}
三, 計(jì)算時(shí)間差
let dateFormatter = NSDateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss"
let timeNumber = Int(dateFormatter.dateFromString(end_time)!.timeIntervalSince1970-dateFormatter.dateFromString(create_time)!.timeIntervalSince1970)
print(self.getHHMMSSFormSS(timeNumber))
四, 最終結(jié)果
48:57:47
